std::allocator

Member functions

allocator::allocator

allocator::~allocator

allocator::address

allocator::allocate

allocator::deallocate

allocator::max_size

allocator::construct

allocator::destroy

Non-member functions

operator==operator!=

 

allocator();	(1)
allocator( const allocator& other );	(2)
template< class U > allocator( const allocator<U>& other );	(3)

Constructs the default allocator. Since the default allocator is stateless, the constructors have no visible effect.

Parameters

other

-

another allocator to construct with

Exceptions

(none)	(until C++11)
noexcept specification:   noexcept	(since C++11)
